The wired connection extends across the junction 320. In a specificexample, a lateral edge of the main display 120 is joined to alongitudinal edge of the secure display 240. The hybrid card reader 252is arranged along the junction 320, with the opening extending along thejunction 320 and the card reader body extending parallel the securedisplay 240. The power source 600 (e.g., battery) is arranged parallelthe main display 120 proximal the main display back surface, proximalthe end of the main display 120 distal the junction 320 (distal maindisplay end). The main processor 110 is arranged between the powersource 600 and the junction 320. The printer 500 is arranged along aportion of the secure display back surface. In a specific example, theprinter 500 is arranged along an end of the secure display back surfacedistal the junction 320 (distal secure display end). The gap of theprinter 500 is oriented to be substantially parallel with the distalsecure display end. The gap includes toothed separation mechanisms 560along both longitudinal edges of the gap. The printer door 540 isarranged distal the secure display back surface, with the hinge 580distal the distal secure display end, such that the printer door 540opens away from the secure display 240. The housing 300 preferablytraces the surfaces of the printer body 510, remainder of the securedisplay back face, and main display 120 to cooperatively form a handle310. The weight of the printer 500 preferably counterbalances the weightof the power source 600. A first contact surface 340 is defined alongthe distal main display end) and a second contact surface 340 is definedalong a longitudinal, arcuate surface of the printer 500 (e.g., alongthe printer body 510 or the printer door 540). A first camera isarranged along the side of the secure display 240, proximal the distalsecure display end, and is oriented with the camera active surfacenormal vector substantially perpendicular the second contact surfacenormal vector (e.g., perpendicular a gravity vector). The paymentterminal 1 can additionally include a power and data connector arrangedbetween the processor and power source 600, along a longitudinal side ofthe main display 120. The payment terminal 1 can additionally include aset of docking connectors arranged along an arcuate surface of theprinter body 510, configured to connect to an external dock. The powerand data connector and docking connectors are connected to the powersource 600. The payment terminal 1 can additionally include a WiFitransceiver configured to communicate with a remote device, an NFCtransceiver, a Bluetooth transceiver, a beacon transceiver, or any othersuitable communication mechanism. The short-range communication modules(e.g., NFC, Bluetooth, beacon, etc.) that function as payment hardwareare connected to the secure processor 210. The long-range communicationmodules are connected to the main processor 110.

In a second example, the payment terminal 1 includes a single display(secure display 240) and a single input device (secure input device230), a main processor 110, a secure processor 210, a secure inputprocessor 220, a power source 600, and a set of payment hardware 250(e.g., short-range communication modules, card reader, etc.). The singleinput device is only connected to and sends information to the secureinput processor 220. The secure input processor 220 is connected to andsends information to the main processor 110 and the secure processor210. The main processor no is connected to the secure input processor220, the power source 600, and the display. The secure processor 210 isonly connected to the power source 600, the payment hardware 250, themain processor no, and the secure input processor 220. The secureprocessor 210 is connected to the main processor no by a power and datacable. The secure input processor 220 is operable between a securedmode, wherein information is sent to the secure processor 210, and anunsecured mode, wherein information is sent to the main processor 110.The secure input processor 220 switches between the secured andunsecured mode in response to a switching event. The switch event can bethe initiation of a payment flow (e.g., in response to selection of a“charge” icon), the receipt of financial transaction information fromthe payment hardware 250, the detected position of the payment terminal1, or any other suitable event. In a first specific example, the paymentterminal 1 can operate in the unsecured mode in response to theaccelerometer indicating a first terminal orientation, and in a securedmode in response to the accelerometer indicating a second terminalorientation (e.g., opposing the first orientation). In a second specificexample, the payment terminal 1 can operate in the unsecured mode inresponse to a switch operating in a first position, and in the securedmode in response to the switch operating in a second position. Theswitch is preferably switched from the first to the second position whenthe terminal 1 is rotated about a rotational axis substantially normalto a terminal contact surface 340.
